Description
If you're building a high-performance engine that demands precision and longevity, KB Performance pistons deliver the tight tolerances and superior ring seal that separate a reliable power plant from a mediocre one. These diamond-machined forgings allow installation at tighter clearances than conventional pistons, reducing piston rock and maximizing combustion efficiency. The T-5 heat-treated 390 hypereutectic aluminum alloy resists thermal stress and extends piston life, making this kit essential for serious racers and engine builders who can't afford failures.
